Technological means solves technical problem, and the realization process for reaching relevant art effect can fully understand and implement.This Shen
Please each feature in embodiment and embodiment, can be combined with each other under the premise of not colliding, be formed by technical solution
It is within the scope of the present invention.
The explanation of following embodiment is to can be used to the particular implementation of implementation to illustrate the present invention with reference to additional schema
Example.Direction term that the present invention is previously mentioned, such as "upper", "lower", "left", "right" etc. are only the directions with reference to annexed drawings.Cause
This, the direction term used is to illustrate and understand the present invention, rather than to limit the present invention.
Further it will be understood that in the VA type liquid crystal display shown using multidomain, by being located on the substrate of side
Pixel electrode cooperate to be formed with the public electrode being located on the substrate of the other side for drive the liquid crystal in display farmland to divide
The electric field of son rotation.And in following each embodiments of the application, it is intended to the structure of pixels illustrated electrode, to the tool of public electrode
Body form does not limit.Without departing substantially from spirit and essence of the invention, public electrode can use arbitrary shape
Formula, such as plane electrode.
In embodiments herein, two kinds of electric field strengths are formed in same pixel region by the structure of pixel electrode
Unequal electric field.When equal electric field does not act on the liquid crystal molecule in pixel region simultaneously to above-mentioned intensity, will make to be located at not
The deflection of different angle occurs for the liquid crystal molecule within the scope of same electric field, realizes optics complementation to improve the mistake of the color under big visual angle
Very.Specifically, each pixel region of pixel electrode is each divided into the first orientation unit and the second orientation unit.Namely
It says, eight orientation units can be correspondingly formed for the pixel electrode comprising four pixel regions.It is utilized respectively each pixel region
The first orientation unit in domain forms the first electric field, forms the second electric field using the second orientation unit of each pixel region, and make
The electric field strength of first electric field and the electric field strength of the second electric field are unequal.It is illustrated below with reference to Fig. 2.
Fig. 2 is the structural schematic diagram of the pixel electrode of the embodiment of the present application.It can be seen from the figure that the pixel electrode 20 has
There are four the pixel region ABCD of area equation, are divided with the stem electrode 21 to intersect vertically, in the outer of pixel electrode 20
Portion edge is additionally provided with the stem electrode 21 of rectangle, i.e., each pixel region is vertically or in the horizontal direction in sphere of movements for the elephants shape
It is adjacent.Stem electrode 21 is mainly used for supporting branch electrodes 22.Branch electrodes 22 are strip shaped electric poles arranged in parallel, and more
Equidistantly distributed between a branch electrodes 22, if the spacing between each branch electrodes 22 is unevenly distributed, liquid crystal display is very
It is easy to appear the uneven phenomenon of display.
Further, multiple branch electrodes 22 are extended radially from multiple places of intersecting vertically of stem electrode 21, relatively
The elongated end of the multiple branch electrodes 22 extended is formed with multiple gaps at the diagonal line of pixel region, and multiple gaps are in big
Cause lineal layout.By taking pixel region A as an example, branch electrodes 22 in the region two apex angles opposite from pixel region A respectively
Position to the internal stretch of pixel region A, the line of demarcation of substantially straight line is formed at the diagonal line of pixel region A.It will be respective
Region comprising two parts branch electrodes 22 is denoted as the first orientation unit A1 and the second orientation unit A2 respectively, such as dotted line in Fig. 2
Shown in the region that frame respectively surrounds.Wherein, the branch electrodes 22 in the first orientation unit A1 are set to sphere of movements for the elephants shape middle position
Stem electrode 21 the place that intersects vertically, the branch electrodes 22 in the second orientation unit A2 are set to sphere of movements for the elephants shape corner position
The place that intersects vertically of stem electrode 21.Pixel region BCD has also done corresponding setting respectively, as shown in Fig. 2, repeating no more.
It should be noted that pixel region ABCD and the first orientation unit being located in pixel region ABCD and
Two orientation units be traditionally arranged to be vertically with form in the horizontal direction respectively symmetrically.As shown in Fig. 2, pixel region A
With pixel region B and the first orientation unit A1 and B1, the second orientation unit A2 and the axisymmetrical of B2 vertically.Together
Reason, pixel region A and pixel region D and the first orientation unit A1 and D1, the second orientation unit A2 and D2 are in the horizontal direction
Axisymmetrical.This is because working condition when VA liquid crystal display mainly generates symmetric deflection using liquid crystal molecule is regarded
The compensation at wild angle, only liquid crystal domain high degree of symmetry arrangement, can just make display of the liquid crystal display on four direction up and down
It is balanced.
In embodiments herein, spacing between the branch electrodes of the first orientation unit in pixel region ABCD with
Spacing between the branch electrodes of the second orientation unit in each pixel region is not desired to.As shown in Fig. 2, the first orientation unit A1
The space D 2 between the branch electrodes 22 in space D 1 and the second orientation unit A2 between interior branch electrodes 22 is unequal.When
It, can be respectively in the first orientation unit due to the influence of space D 1 and D2 when being applied to pixel electrode 20 with certain gray scale voltage
The electric field of electric field strength not etc. is formed in the range of A1 and the second orientation unit A2.It is formed between pixel electrode and public electrode
The intensity of electric field be generally dependent on thickness (each layer liquid crystal of the numerical value for the gray scale voltage being applied on pixel electrode, liquid crystal cell
The resultant effect of working condition) and bump and/or slit (slit) on pixel electrode size.Since the application is implemented
The numerical value for the gray scale voltage being applied on pixel electrode 20 and the thickness of liquid crystal cell in example are equal, therefore, the first orientation list
Member and the intensity of the electric field within the scope of the second orientation unit are determined by the size of the slit on pixel electrode 20, i.e., by branch electrodes
The size of spacing between 22 determines.
Fig. 3 is the distribution schematic diagram that the embodiment of the present application is formed by electric field.As shown in figure 3, being formed at space D 1
Electric field electric field line distribution it is more dense, i.e. the intensity of electric field within the scope of pixel unit A1 is greater than within the scope of pixel unit A2
Electric field intensity.Liquid crystal molecule and the second orientation unit under the influence of above-mentioned electric field, within the scope of the first orientation unit A1
The deflection of different angle will occur for the liquid crystal molecule within the scope of A2, i.e. pixel region A can be respectively formed two display farmlands.Into one
Step, the spacing between branch electrodes 22 in the first orientation unit of pixel region BCD and in the second orientation unit is respectively
D1 and D2, and the unequal electric field of intensity will be also formed in pixel region BCD respectively.
Fig. 4 is the transmitance of VA type liquid crystal display and the relation schematic diagram of wavelength.As shown, horizontal axis is wavelength, indulge
Axis is transmitance, and Δ nd is the overall target for influencing the transmitance of VA type liquid crystal display, and wherein Δ n indicates the birefringent of liquid crystal
Rate, d indicate that liquid crystal cell is thick (resultant effect of each layer liquid crystal working condition).As can be seen that with the increase of Δ nd, liquid crystal display
The transmitance of device and the dependence of wavelength are more obvious, and the original white balance after RGB colour mixture of liquid crystal display is broken,
Different degrees of cross-color will thus be generated.There is liquid crystal molecule in the range of 360 degree as careful as possible and impartial
Orientation is the major way for improving cross-color using optical compensation is carried out between the light of different wave length.By by four pixels
Region (orientation of four kinds of liquid crystal molecules) is further divided into eight orientation units, and making tool, there are four the pixel electrodes of pixel region
20 can be shown with eight farmlands, and then effectively improve the cross-color of large size liquid crystal display.
In addition, in compared with the prior art by the different piece to same pixel region apply different driving voltages into
The mode (as shown in Figure 1) that eight farmland of row is shown, due to not needing that driving circuit is respectively set, thus can simplify manufacturing process with
And driving method, while improving the aperture opening ratio of pixel.
Further, as shown in Fig. 2, when D2 is greater than D1, the electric field strength in the first orientation unit A1 will be greater than second
Electric field strength in orientation unit A2, therefore the deflection angle of the liquid crystal molecule within the scope of the first orientation unit A1 is greater than second and matches
The deflection angle of liquid crystal molecule into unit A2.And the deflection angle of liquid crystal molecule is bigger, the light penetrated from liquid crystal layer
Line is more, i.e. the transmitance of liquid crystal display is higher, and the brightness of liquid crystal display is bigger, the picture of display it is more beautiful with it is clear
It is clear.Therefore can be by adjusting the spacing between branch electrodes 22, and then the transmitance of liquid crystal display is adjusted to meet display
Requirement.
It can also be seen that the line of demarcation of the first orientation unit A1 and the second orientation unit A2 is approximately through pixel from Fig. 2
The diagonal line of region A, the i.e. area of the first orientation unit A1 are equal to the area of the second orientation unit A2, that is to say, that can recognize
It is equal with the quantity of liquid crystal molecule in the second orientation unit for the quantity of the liquid crystal molecule in the first orientation unit.In the application
Other embodiments in, the area that can also adjust the first orientation unit A1 and the second orientation unit A2 is unequal.Orientation unit
The liquid crystal molecule for being included in range is more, and the light penetrated from liquid crystal layer is more, and the transmitance of liquid crystal display is higher, liquid
Crystalline substance screen brightness it is bigger, the picture of display it is more beautiful with it is clear.Therefore, in order to make liquid crystal display meet display want
It asks, it can be according to analog simulation as a result, the first orientation of size and/or change for passing through the spacing between adjusting branch electrodes 22
The area of unit and the second orientation unit is realized.
It is also to be noted that due to the direction one of liquid crystal molecule in the first orientation unit A1 and the second orientation unit A2
It causes, therefore the first orientation unit A1 and the second orientation unit A2 transposition is arranged, that is to say, that make the first orientation unit A1
The space D 1 of interior branch electrodes 22 is greater than the space D 2 of branch electrodes 22 in the second orientation unit A2, or makes the first orientation unit
The area of A1 is greater than the area of (or being less than) second orientation unit A2, or changes simultaneously the spacing and orientation between branch electrodes
Same adjustment effect also may be implemented in the area of unit.
Fig. 5 (a)-(b) is the structural schematic diagram of the pixel electrode of the application other embodiments.As shown, by branch's electricity
The line of demarcation that gap between the elongated end of pole is formed by orientation unit is no longer at the diagonal line of pixel region.In Fig. 5
(a) in, which has the form of substantially broken line.The pixel electrode 20 of this structure is conducive to the face to the first orientation unit
Long-pending and the second orientation unit area is finely adjusted.In Fig. 5 (b), which has the form of substantially camber line.In general,
The boundary of continuous and derivable can make electric fields uniform, and then make the orientation consecutive variations of liquid crystal molecule, be conducive to improve liquid crystal display
The display effect of device.Therefore the preferential structure using the pixel electrode with smooth boundary line.Further, by branch electrodes
Elongated end between gap be formed by orientation unit line of demarcation can also be use other forms, if guarantee, be located at
The area equation of each first orientation unit in different pixels region, and each second orientation unit positioned at different pixels region
Area equation, so that it may so that liquid crystal domain is symmetrical, and then realize the purpose for improving cross-color.
Pixel electrode in the embodiment of the present application can be improved the aperture opening ratio of pixel and improve the color under big angle of visibility
Distortion.Due to not needing to carry out subregional voltage driving to pixel electrode, manufacturing process and driving circuit can simplify
Design, reduce the cost of production, promote the competitiveness of product.
